A self-professed Christian who labors under the mistaken impression that Christians are persecuted in this country, and that he or she is commonly persecuted for his or her beliefs. These people usually attempt to convert everyone they know or meet to their own denomination of "born again" Christianity, thereby alienating a number of non-Christians as well as Christians of denominations not of their own, then attribute their subsequent shunning by society to a fictitious, widespread anti-Christian mania.

Josh: "Hi, my name is Josh, and I'm a Jesus freak."
Tim "Hi, my name is Tim, and I'm Jewish."
Josh: "You need the love of Jesus in your life! Repent! You're going to hell!"
Tim: *walks away*
Josh: "Why do you hate me? Why must I be persecuted?!"

A person who supports and believes in Christianity, often to the degree where it's overwhelming, irritating, and even creepy. Some pass out pamphlets promoting God or Christ, plead with you to come to church, and sport stickers or T-shirts promoting their God, whom they've never seen physical proof of. Sometimes they'll even try to force their beliefs on you, so if you're an atheist, beware.

Jesus freak: "Come to church, it won't hurt. Jesus loves you. He died for your sins."

5: tries to foist an extreme form of christianity off on others
6: is a born-again christian and/or fundamentalist

People of the Christian faith who become fanatical in their beliefs, eventually driving away friends with different religions, sexual preferences, ect. Note that not all Christians are like this.

While these people aren't "Bad" people,they are usually intolerant to others religious beliefs. They tend to tell those of other religion that they are going to Hell and that they need to convert to Christianity. These can also be those who preach about their respective denominations. There is also a possibility that they could be homophobic.
